What Kling 4.0 Flash Does

Kling 4.0 Motion for Fewer Tokens

Flash uses 16 tokens per second on GoEnhance, compared with 29 for Kling 4.0 at 720p, so the same budget covers more takes.

Single Takes up to 20 Seconds

Pick any length from 3 to 20 seconds and get one continuous shot, long enough for a full action beat.

Native Audio in Every Clip

Footsteps, engines, crowds and music are generated with the video. Audio is always on.

Start From a Photo

Upload one image and Flash uses it as the first frame, keeping your photo's framing. Last frames are not supported; use Kling 4.0 or Gemini Omni 1.2 Flash for those.

Up to 10 Reference Images

In reference to video, add people, products or places as references and name them in the prompt to keep them consistent from shot to shot.
